Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549512, here are decompositions:

3 + 549509 = 549512
31 + 549481 = 549512
109 + 549403 = 549512
181 + 549331 = 549512
193 + 549319 = 549512
199 + 549313 = 549512
283 + 549229 = 549512
349 + 549163 = 549512

Showing the first eight; more decompositions exist.
